A Robot Used for Partial Discharge Detection of Switchgear

This paper describes a robot used for partial discharge (PD) detection of the High Voltage switch cabinet in substations. The robot, mounting a 5-DOF manipulator, carrying an integrated partial discharge detection sensor, automatically detects the partial discharge state of the switch cabinet. It is also featured with autonomous vision navigation, automatic positioning of detection points, automatic partial discharge detection and automatic recording discharge images, and it is remotely controlled by a wireless system. This paper introduces the overall technical scheme of the robot, and discusses the key technology of the robot. Now the robot is successfully applied in several substations to demonstrate its performance.
